’Twas the night … for less screen time. New research reveals that time spent on lighted devices hurts your chances for a good night’s rest. The study involved only 12 subjects, but those who read an iPad before bed instead of a book fell asleep later and showed lower melatonin, critical to our circadian rhythms. Sleep loss is linked to loads of health issues. So settle down for that long winter’s nap in low-tech fashion … and to all a good night.
